JohnAB Posted December 11, 2011 Report Share Posted December 11, 2011 I have the DC9310 7.2-18 V charger that came with my DC9181 Type 1 18V Li Ion Compact battery packs. They are less than two years old and do not have very many cycles on them. I used them recently and both batteries had a very short run time (<1 minute). I put them in the recharger and got the blinking light indicating charging. It eventually turned on continuous indicating Charged. I put the battery in the drill and it ran at high speed less than 5 seconds and stopped. I recharged again and this time the drill did not work at all. Voltmeter on the battery indicates nothing. I have tried several cycles on the charge and overnight and still no charge. The indicator light says it is charging and then is charged. I have 2 batteries and the same thing happens with both. How do I know if the recharger is not really charging event though the lights work? I'd certainly hope the Li Ion batteries would last longer than 2 years. The drill does work fine with NiMH battery pack. Thanks for the help. John Quote Link to comment Share on other sites More sharing options...
